Dress code for exams

There is no such prescribed dress code for examination. Students  can choose as per their convenience.

There isn't any dress code as of now but what I think is that people shouldn't wear night suits also like you mentioned before during such exams. Nightsuits doesn't justify professionalism in any sense and wearing formals may suggest a little of the professionalism 

Is it ok to wear shorts to ca examination centres if u r hurt on the leg or some injury happens. I mean i hope i won't be debarred for wearing shorts to the examination centre. Just asking to know the rules.
